TOOL FOR TIGHTENING AND SECURING HOSE-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 665,803, dated January8, 1901.

Application filed March 19, 1900. Serial No. 9 ,319. (No model.)

To all whom it may concern.-

Be it known that I, JAMES F. SARGENT, Jr., a citizen of the UnitedStates, residing at Lowell, in the county of Kent and State of Michigan,have invented new and useful Improvements in Tools for Tightening andSecuring Hose-Couplings, of which the following is a specification.

My invention relates to a new and useful I0 tool for tightening andsecuring straps for securing hose couplings; and the invention consistsin a combination of a pair of jaws adapted to be opened by pressingtogether the handles or levers, the jaw which I term the lower jawhaving an upward curve adapted to project above and in front of theupper jaw when the jaws are closed.

It also consists in the peculiar construction of the lower jaw,hereinafter fully described. The objects of my invention are, first, toconstructa tool for the purpose specified which can be readilyandquickly applied, and, second, to so construct the jaws that when theyare closed they can be readily inserted into the loop of thehose-fastener. These objects I accomplish by means of the mechanismillustrated in the accompanying drawings, in which- Figure 1 is a sideView showing the position of the tool during the first step in theoperation of attaching the strap to a hose, the latter being shown insection. Fig. 2 is a similar view showing the position of the jaws ofthe tool after the last step in the operation of attaching the strap.Fig. 3 shows a side elevation of the device with the jaws slightly open.Fig. 4 shows a side elevation of the lower jaw. Fig. 5 shows a sectionalview on line X X of Fig. 2, and Fig. 6 shows a plan view of a portion ofthe handle of the lower jaw with its end provided with a tack-puller ornailextractor.

Similar letters refer to similar parts throughout the several views.

A shows the upper jaw, and B shows the lower jaw. The upper jaw iscurved to fit into the lower, so that when the jaws are closed the uppersurfaces of the jaws lie, preferably, in the same plane. The outer endof the lower jaw B is curved upwardly,

so that when the jaws are closed the said outer end of the lower jawwill overhang or project above and in front of the jaw A, thus forming ahook which is adapted to engage with the loop of the hose-coupling strapW, 5 '5 The lower jaw Bis provided with a handle D and with astrengthening-flange F, the latter being shown in Figs. 2, 3, and 4; butthis flange may be omitted, if desired. When the jaws are closed, thejaw A lies by the side of the flange F and fits or rests upon the jaw B,

as shown in Fig. 4.

E is the handle of the jaw A.

C is a rivet or bolt securing the jaws and levers together.

I prefer to construct the lower-jaw handle D with the tack-puller 'I.

The operation of my invention is as follows: The coupling-strap W isfirst applied to the hose H. The front end of the jaw B, projectingslightly above the jaw A, forms a hook which can be placed under theloop or between the loops or ends of the fasteningstrap, and the handlesE and D being pressed together open the jaws and tighten the loop uponthe hose.

By my construction the tool is always in condition when closed to beinserted into the loops, and by pressing together the handles E and Dthe coupling-straps are tightened upon the hose. Afterward the other endof the strap is drawn over in the ordinary manner.

The advantages of my invention are as follows: First, the tool is inposition to engage with the coupling-strap when the jaws are closed;second, by the use of the flange F the lower jaw is strengthened and theupper jaw fits into the lower jaw, so as to allow the front end of thelower jaw to extend slightly go beyond the front end of the upper jaw,thereby forming a suitable engagement with the c0upling-strap; third, byproviding the tackpuller upon the lower jaw the tool may be used formore than one purpose. 5

In order to secure a more complete engagement between the jaws and thesecuringstrap, I propose to provide the jaws with notches, the notchesin the upper jaw being shown by N and in the lower one by N.

Having thus described my invention, what I claim to have invented, anddesire to secure by Letters Patent, is-

l. A tool of the class described comprising a pair of jaws pivotedtogether and having operating-handles, one of said jaws having its endextended beyond and overhanging the end of the other jaw to constitute ahook for engagement with the loop of a hose-strap, and suitable engagingmeans for said loop on the outer surface of the jaw having the said endextension.

2. In a tool of the class described, the combination of an upper jaw, alower jaw pivoted thereto and having its end curved upward and extendedbeyond the front end of the upper jaw to constitute a hook when the jawsare closed, said lower jaw being provided with a notch on its outerconvex surface near the end of the jaw, and handles for opening andclosing said jaws.

3. In a tool of the class described, the combination of an upper jaw, alower jaw pivoted thereto and having its end curved upward and extendedbeyond the front end of the upper jaw to constitute a hook when the jawsare closed, for the purpose specified, suitable engaging means for ahose-strap, on the outer surface of the lower jaw near the end thereof,a flange on one side of said lower jaw, and handles for opening andclosing said jaws, substantially as described.

4. A tool ofthe class described, comprising a pair of jaws pivotedtogether and having operating-handles, one of said jaws having its endextended beyond and overhanging the end of the other jaw to constitute ahook for engagement with the loop of a hose-strap, and suitable engagingmeans for said loop on the outer surface of each jaw, substantially asdescribed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
